If Magness was actually chosen to be Salazar's assistant coach, he would have known about the the possible PED use in it's entirety. The fact that in his entire time there he only has one piece of evidence supporting his claims makes me suspicious. You would think that the assistant coach would have a more inside look at the happenings behind the scenes. He would have been there for many workouts, meetings, talks with Alberto that would have given him a more concrete insight as to what was happening. We know Alberto has all his athletes on Thyroid medication. We know this. The possibility of microdosing is very real but there's just no evidence to support this.
